ABSTRACT:
Various systems and methods are provided for minimizing an inrush current to a load after a voltage sag in a power voltage. In one embodiment, a method is provided comprising the steps of applying a power voltage (100) to a load (246), and detecting a sag in the power voltage (106) during steady-state operation of the load. The method includes the steps of adding an impedance (RT) to the load upon detection of the sag in the power voltage, and removing the impedance when the power voltage has reached a predetermined point in the power voltage cycle after the voltage has returned to normal.
